Don't wait 5 days to see your surgeon and don't let your surgeon pooh pooh any concerns you have. I lost both my expanders to massive infection I came home from the hospital with. My surgeon kept telling me my "fever" was normal for healing, even though he never stuck a thermometer in my mouth. So I couldn't differentiate "healing" pains from the pain from the drains that were infected. Don't ever stop questioning what you don't feel is right...they're not gonna do it for you...you have to be on top of what your body is feeling or not feeling.
I had that same problem, turned out to be the drain laying against a nerve. If I moved a certain way it just about brought me to me knees. As soon as the drain was removed the pain went away.....
Having more pain than usual is a reason to be in touch with your surgeon. It well could be related to the drain; but it's not inconceivable that there could be other healing problems, such as infection. You should not hesitiate to contact the surgeon.
Dear laurel 13: You may be right. It may just be a positional thing related to the placement of the drain. You should not be shy about letting your surgeon know about the pain. Depending on the severity, he may want to see you sooner.
